The pickup unit consists of pickup and transport rollers. When the Start Key signal or Original Feed signal is input, the ADF motor (M2001) turns in the normal
direction and then the pickup solenoid (SL2001) turns on. The pickup unit lowers and the pickup and transport rollers rotate to feed the paper. The shutter moves
up in conjunction with the pickup unit. A separation pad is used to prevent multiple sheets from being fed at the same time.
When the original reaches the registration roller where is it looped, the pickup solenoid (SL2001) turns off and the pickup unit roller rises. Next the registration
solenoid (SL2002) turns on and the original is fed by the registration roller. At this time, the pickup roller drive shaft which is rotated via the spring one-way clutch
is stationary at the highest position in the pickup unit. The pickup roller incorporating a one-way clutch is rotated by the friction against the paper.

There are two types of reversal operations, reversal from the top side to the reverse side and reversal from the reverse side to the top side. However, since their
operating principles are the same, only reversal from the top side to the reverse side is described below.
a. When the ADF motor (M2001) turns and the registration solenoid (SL2002) turns on, the registration roller turns to feed the paper along the platen guide for
surface scanning. After completion of scanning, the paper is fed to the delivery unit by the transport roller 1 and delivery roller.
